- there is little information loss given a compression ratio of 2, 4, and 8;

- **Efficient**

- it drastically reduces the GPU consumption of KV cache;

- **Compatible**
|
15 |
-
- it can work together with position extrapolation (e.g. YaRN) to further extends the context length; it can also work with grouped query attention to further reduce the KV cache size;

- **Low-Cost**
